, CELLULAR INJURY & ADAPTATION
Focus: mechanisms, clinical manifestations, and pathophysiologic reasoning.
1. A patient with long-standing hypertension develops left ventricular enlargement. Which cellular
adaptation best explains this finding?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B. Hypertrophy
Rationale: Cardiac myocytes respond to chronic pressure overload primarily by increasing cell size, producing
hypertrophy.
2. Which process occurs when a cell is exposed to a persistent stress and changes into another
mature cell type better able to tolerate the stress?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Necrosis
Correct Answer: C. Metaplasia
Rationale: Metaplasia is a reversible change in which one differentiated cell type is replaced by another mature cell type
better suited to the stress.
3. Which finding is most characteristic of apoptosis?
A. Uncontrolled cell swelling with inflammation
B. Programmed cell death with cellular fragmentation
C. Immediate tissue infection
D. Universal loss of ATP
Correct Answer: B. Programmed cell death with cellular fragmentation
Rationale: Apoptosis is regulated cell death and generally occurs without the marked inflammatory response associated
with extensive necrosis.

,4. A cell loses its ability to maintain ATP-dependent ion gradients during severe ischemia. What is an
early consequence?
A. Cellular swelling
B. Increased protein synthesis
C. Increased oxidative phosphorylation
D. Immediate fibrosis
Correct Answer: A. Cellular swelling
Rationale: ATP depletion impairs membrane pumps such as the sodium-potassium pump, causing intracellular sodium
and water accumulation.
5. Which reactive molecule is strongly associated with oxidative cellular injury?
A. Free radical
B. Albumin
C. Insulin
D. Bicarbonate
Correct Answer: A. Free radical
Rationale: Reactive oxygen species and other free radicals can damage lipids, proteins, and nucleic acids.
6. Why can reperfusion after prolonged ischemia paradoxically worsen cellular injury?
A. Reoxygenation can generate reactive oxygen species and inflammatory responses
B. Oxygen permanently blocks ATP production
C. Reperfusion always prevents inflammation
D. Blood flow stops all immune activity
Correct Answer: A. Reoxygenation can generate reactive oxygen species and inflammatory responses
Rationale: Restoration of oxygen can generate reactive oxygen species and activate inflammatory pathways, contributing
to reperfusion injury.
7. Which cellular change describes a reduction in cell size due to decreased workload or inadequate
nutrition?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: A. Atrophy
Rationale: Atrophy is a decrease in cell size and often occurs with reduced workload, denervation, poor nutrition, or
reduced blood supply.

, 8. Coagulative necrosis is most commonly associated with ischemic injury in:
A. Most solid organs except the brain
B. The brain only
C. The pancreas only
D. The skin only
Correct Answer: A. Most solid organs except the brain
Rationale: Coagulative necrosis is typical of ischemic injury in most solid organs; brain ischemia classically produces
liquefactive necrosis.
9. Liquefactive necrosis is classically seen in:
A. Brain infarction and some bacterial infections
B. Myocardial infarction only
C. Bone remodeling
D. Normal liver tissue
Correct Answer: A. Brain infarction and some bacterial infections
Rationale: Enzymatic digestion of tissue produces a liquid consistency in liquefactive necrosis, classically in CNS infarcts
and some infections.
10. What is a major consequence of mitochondrial injury?
A. Reduced ATP generation
B. Increased oxygen delivery to every cell
C. Guaranteed normal ion gradients
D. Increased protein folding in all cells
Correct Answer: A. Reduced ATP generation
Rationale: Mitochondria generate ATP; injury can reduce energy production and contribute to loss of cellular
homeostasis.
